Floating like a balloon and as blue as the sapphire safely nestled in its side, the Ballon Bleu <b>watch</b> by <b>Cartier </b>adds a dash of elegance to any wrist. Roman numerals are guided on their path by a sapphire cabochon winding mechanism guarded by an arc of precious metal. The convex curves of the case, guilloché dial, sword-shaped hands, and luxurious detailing ensure that the Ballon Bleu watch by Cartier floats within the world of Cartier watchmaking. <b>Each Cartier creation is available to order online using our Click & Collect service at Selfridges London. You will collect your order, presented in the iconic red box, at the Cartier boutique in The Wonder Room.</b>
